Northern Irish star Jamie Dornan is concerned about his friends' reaction to his raunchy role in Fifty Shades Of Grey.

The model-turned-actor is sure his father will be fine with his portrayal of saucy businessman Christian Grey, but is worried about what his pals will say when the film comes out.

He tells The Observer Magazine, "I'm more concerned about my mates. More concerned about the ribbing (teasing) I'll get. We're all quite harsh with each other, in a lovely, known-each-other-all-our-lives way."

The film is due for release in February (15).
